Should `format_to_n` has the same detection as `format` and `format_to`?

[owent]

template <typename... T>
FMT_INLINE auto format(format_string<T...> fmt, T&&... args) -> std::string {
  return vformat(fmt, fmt::make_format_args(args...));
}


template <typename OutputIt, typename... T,
          FMT_ENABLE_IF(detail::is_output_iterator<OutputIt, char>::value)>
FMT_INLINE auto format_to(OutputIt out, format_string<T...> fmt, T&&... args)
    -> OutputIt {
  return vformat_to(out, fmt, fmt::make_format_args(args...));
}


template <typename OutputIt, typename... T,
          FMT_ENABLE_IF(detail::is_output_iterator<OutputIt, char>::value)>
FMT_INLINE auto format_to_n(OutputIt out, size_t n, format_string<T...> fmt,
                            const T&... args) -> format_to_n_result<OutputIt> {
  return vformat_to_n(out, n, fmt, fmt::make_format_args(args...));
}

Should const T&... args be T&&... args here?

Yes, good catch.
